CARTER, OF JOHNSON CITY, TENNESSEE, ASSIG-NORS TO AMERICAN GLANZSTOFF CORPORATION, OF NEW YORK, N'. Y., A CORPORATION OF DELAWARE SEALING JYIIEANS Application led August 20, 1931. Serial No. 558,310.

Our invention relates to a liquid seal to be used in wash tanks, and more particularly to provide an effective seal between the bottom tier of spools and the openings in the tank.

One object of our invention is to construct a new type of acid resistant sealing means Vto be used in washing or treating tanks which will, more effectively and efficiently produce those desirable results which should be obtained in the washing of spools, having artificial threads or filaments or other threads or filaments woundA thereon, by means of either a vacuum or pressure system.

Another object of our invention is to provide means which will effectively produce a seal between the washing or treating tank and the lowermost tier of spools so that, when a pressure or a vacuum washing system is used there will be no leakage therebetween.

A furtherobject of our invention is to so construct a sealing means which will prevent any of the acid used in the washing or treating of the threads or any of the acid adhering thereto from collecting around the sealing means and causing those threads on the lowermosttier of spools and also the spools to be damaged or otherwise rendered useless.

Other objects will become more apparent from a perusal of the following description.

and a study of the drawing in which: Figure l is a view in cross-section taken along lines 1--1 of Figure 2, showing the annular sealing gasket or ring situated in the bottom of a washing or treating tank with a spool inposition thereon; and

Figure 2 is a top plan view of the sealing gasket or ring.

In the manufacture of artificial filaments or threads, it is customary, in certain processes, to collect the said filaments or threads upon a foraminated or perforated spool, and

.while thereon, to subject them to washing,

ment. These spools carrying the yarn areplaced in tiers in a suitable tank, each stack of spools fittingl around an .opening 1in the tank. A cap is placed on the top spool of each stack and the filaments or threads undergo several treatments by either forcing the treating liquid through the foraminated or perforated spools and the layers of threads or filaments, or by filling the tank with the treating liquid and by vacuum sucking the treating liquid through the layers and spool. The present invention has to do with a ring or gasket of novel construction by means of which the bottom edge of a spool upon which the filaments or threads have been wound may be held liquid tight against the bottom of the tank in which the-treating operations are to take place.

Referring now to Figure l, we have shown the bottom l of a washing or treating tank 2. The tank 'is made of any suitable material, preferably steel, and the bottom thereof is lined with rubber or any suitable lining'material 8. Provided at spaced intervals at the bottom of the tank are openings 4 which permit of communication with a vacuum or pressure means (not shown).

The annular sealing gasket or ring 5 comprises an annularly shaped member 6, formed ber 6 are a plurality of upstandng centering.

means or lugs 8 which are'positioned inwardly from lthe periphery thereof. These lugs aid in the centering of the spools upon the gasket. These lugs, as well as the top portionof the gasket or ring, slope inwardly toward the center of the member 6 where there -isforme'd an opening or bore 7 and which extends through the projection 11 and communicates with the tube. It will readily be appreciated, that by this construction all of the treating liquid will be drained away,

thus effectively preventing the accumulation ing downwardly from the periphery to the of any of the treating liquids around the bore.

seal for a ring 14 made of soft rubber. RALPH H. CARTER.

This ring is vulcanized, cemented or otherwise secured in position and thus becomes,

in eii'ect, an integral portion of the gasket or 10 ring. The periphery thereof is liush with the 75 periphery of the hard rubber portion as is clearly shown in Figure 1.

To assemble the device a suitable sealing ring 13 is placed in the tank around an opening 4. The composite gasket is next placed 80 in the tank, the portion 11 projecting through the opening being secured in place by means of any conventional locking means 18. A spool 16 is then positioned on the gasket and is accurately located in position by 85 means of the lugs 8. The beaded edges 17 of the spool rest upon the soft rubber portion and due to the weight of the spool these edges are imbedded in the soft rubber. When suction or pressure is applied thereto, liquid is 9G forced either inwardly or outwardly through the -foraminated spool and through the lilaments wound thereon.

From the above description it will be readily appreciated that there will be no leak- 95 age between the beaded edges of the spool and the soft rubber portion of the gasket. Thus there will be no loss of pressure or suction as the case may be.

It is understood that our invention is not limited to the precise construction shown, but that it includes within its purview whatever changes come within the .terms or spirit of the appended claims.

Having now set forth our invention as required by the patent statutes, what we desire to claim is:

1. A sealing means for use in the liquid treatment of Va tier of spools, including a cir' cular base member upon which the bottom spool of the tier rests, a centrally formed bore in said base, a plurality of spaced upstanding spool centering lugs extending so from the bore toward the periphery'of the base member; the said lugs and the surfaces of the base member therebtween sloping downwardly from the periphery to the bore.

2. A sealing means :for use in the liquid treatment of a tier of spools, including a cir- 12o l cular base member embracing a sealing means upon which the bottom spool of the tier rests, a centrally formed bore in. said base, va plurality of spaced upstanding spool centering lugs extendingfrom the bore tol 125 ward theperipher'y of the base member, the base portion being undercut with respect to the lugs to form a. recess in which said sealing means rests; the said lugs and the sul'- faces of the base member therebetween slop- 13
